SBS 2003 R2 and VPN issues

I am having problems getting vpn clients connecting to small business server 2003 R2. All ports as prescribed are opened on the D-Link protecting server.On the server site I get the following error message:1. "A connection between the VPN server and the VPN client 68.147.192.196 has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets."2."The user connected to port VPN5-4 has been disconnected because the authentication process did not complete within the required amount of time."

I tried connect from both protected feed and unprotected. Same outcome.Any suggestions?
